What might 9 JOHNSONS FIELD be worth now?

9 JOHNSONS FIELD might now be worth an estimated £746,797.

This is based on house price inflation of 425.9%, between April 1998 and March 2026, for detached houses, in the Milton Keynes local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 425.9% inflationary increase is applied to the most recent sale price for 9 JOHNSONS FIELD of £142,000 on 2nd April 1998. For the value to have increased from £142,000 to £746,797 over the 28 years and one month to March 2026, the following assumptions must hold true:

  • The value of 9 JOHNSONS FIELD has moved in line with the HPI for detached houses in the Milton Keynes local authority area.
  • The April 1998 sale price of £142,000 represented a fair market value for the property.
  • The size, condition, and specification of 9 JOHNSONS FIELD has not materially changed since April 1998.
